your going to need some way of pressing out the bearings as they are pressed in very tight we use a hydrolic press capable of pressing 10tonne of pressure if you have i am guessing its brake drums to the rear not discs remove rear wheels Remove center dust caps the center nuts remove brake drums Remove circlips securing bearing into drums then press out the bearings towards the circlip end until bearing pops out refitting is reversal of removal and adjust rear brakes fit new nuts pein the nuts into the the grove of the stubs as seen before removal fit new dust caps
